Panel of Civil Contractors: Mine Water Ingress Control NEW

The Council for Geoscience (CGS), a Schedule 3A public entity, is establishing a panel of contractors to implement and construct ingress control measures over a three-year period, on an as-and-when-required basis. The core work involves civil engineering solutions that prevent surface water from entering abandoned underground gold mine workings in the Witwatersrand Mining Basin. Water ingress into these voids drives flooding, pumping dependency, and decant to the surface, which in turn causes acid mine drainage and environmental harm. Many of the historic mining-house canals built to divert water have fallen into disrepair or been damaged by illegal mining, and the CGS has identified multiple projects for implementation over several financial years.

The panel will be used as a framework rather than a single contract. Each project will be procured through a brief Request for Quotation (RFQ) issued to all panel members, which will include project-specific scope of work and a Bill of Quantities. Expected works include earthworks, channel and canal construction, and road construction, with the aim of reducing the volume of surface water entering mine voids and proposing long-term solutions to reduce reliance on pumping. Bidders must provide verifiable, signed practical completion certificates for similar civil works. Mandatory requirements include a valid CIDB grading of 3CE or higher (joint venture partners must each provide CIDB proof, with the CIDB JV calculator applied), CSD registration, tax compliance (SARS TCS PIN or CSD number), and a valid COIDA certificate. Functional evaluation is scored out of 100, with a minimum threshold of 75 points for panel inclusion. Points are awarded for at least three completion certificates (35 points), a Project Site Agent with a National Diploma in Civil Engineering or higher and at least four years' relevant experience (35 points), and a Health and Safety Officer with a valid SACPCMP CHSO registration or equivalent safety qualification and at least four years' experience (30 points). Key personnel must be maintained for the contract's duration.

For contractors, the panel offers a three-year pipeline of government-funded civil infrastructure work tied to environmental remediation in a high-profile mining region. Successful bidders gain access to multiple project opportunities without re-tendering each time, and the preference point system (80/20 or 90/10 under the PPPFA) gives credit to businesses with strong specific-goals ownership profiles. Important conditions include: submissions must be sealed and deposited in the tender box at 280 Pretoria Street, Silverton, Pretoria by 11:00 on 25 November 2026; the original document plus two copies must be submitted; a non-compulsory virtual briefing takes place on 5 November 2026 at 11:00; no upfront or deposit payments will be made, with payment due within 30 days of invoice; and performance security must be provided within 30 days of award. Bidders should review the full tender pack carefully, as non-compliance with administrative requirements leads to disqualification.
